Fixable & Non-Fixable Neuronal Terminal Dyes - SynaptoGreen™ & SynaptoRed™

Fixable & Non-Fixable Neuronal Terminal Dyes - SynaptoGreen™ & SynaptoRed™

Cambridge Bioscience offers neuronal terminal dyes that can be used simultaneously for the independent imaging of vesicles localised at neuromuscular junctions and synapses. Offered as individual products or in self-contained nerve terminal staining kits, SynaptoGreen™ and SynaptoRed™ provide different staining “on” rates and de-staining “off” rates based on the length of the lipophilic carbon chain and charged group substitutions. These dyes are available with different water solubility and staining characteristics.

SynaptoGreen™ C4 Chemical Structure

SynaptoGreen™ probes contain a single double bond as shown below. The carbon number following the name SynaptoGreen™ designates the length of the lipophilic tail.

SynaptoRed™ C2 Chemical Structure
SynaptoRed™ probes contain three double bonds as shown below. The carbon number following the name SynaptoRed™ designates the length of the lipophilic tail.SynaptoRed C2


Fixable Nerve Terminal Dyes
We also offer a range of fixable nerve terminal dyes known as the AM dyes. Based on SynaptoRed™ and SynaptoGreen™, these dyes have an additional formaldehyde-fixable amino group attached to the positively-charged head group of the dyes. AM2-10, AM1-43 and AM1-44 are derivatives of SynaptoGreen™ with relatively shorter wavelengths and AM4-64 and AM4-65 are derivatives of SynaptoRed™ with relatively longer wavelengths.

Nerve Terminal Staining Kits
The SynaptoGreen™ and SynaptoRed™ dyes are offered within a portfolio of nerve terminal staining kits. These kits contain various combinations of SynaptoGreen™, SynaptoRed™, ADVASEP-7, AM1-43, SCAS and sulforhodamine 101.
ADVASEP-7
ADVASEP-7 is a sulfonated b-cyclodextrin derivative that has been reported to reduce background fluorescence when using SynaptoGreen™ C4 to stain brain slices.
AM1-43
AM1-43 is a fixable, activity-dependent fluorescent nerve terminal probe. Functioning in a similar way to SynaptoGreen™, it is also fixable. This makes it a useful tool for studying synapses where subsequent fluorescent immunochemistry is desired. Both AM1-43 and FM1-43® have identical excitation and emission wavelengths.
SCAS
SCAS is a quencher designed to reduce background fluorescence when using either SynaptoGreen™, SynaptoRed™ or the fixable AM dyes. Unlike ADVASEP-7, SCAS dramatically lowers background fluorescence as soon as it is added to the preparation without the need for repeated washings.
Sulforhodamine 101
Sulforhodamine 101 has been primarily used as a polar tracer for the study of neuronal cell morphology and cell-cell communications. It also has a potential use in cancer drug screening.
